ShellAppMonitor now always assocates windows with desktop files
Track all windows; at the time of opening (and shell startup) we call into ShellAppSystem to take the WM_CLASS property and try to find an associated .desktop file. Add mozilla-firefox to the list of our WM_CLASS workarounds. Add shell_global_get_screen, since it's often used.
